Local steroid therapy in painful orthopaedic conditions

A double-blind randomised controlled study comparing subacromial injection of tenoxicam or methylprednisolone in patients with subacromial impingement

We have carried out a prospective double-blind randomised controlled trial to compare the efficacy of a single subacromial injection of the non-steroidal anti-inflammatory drug, tenoxicam, with a single injection of methylprednisolone in patients with subacromial impingement. A total of 58 patients were randomly allocated into two groups. Group A received 40 mg of methylprednisolone and group B 20 mg of tenoxicam as a subacromial injection along with lignocaine. The Constant-Murley shoulder score was used as the primary outcome measure and the Disability of Arm, Shoulder and Hand (DASH) and the Oxford Shoulder Score (OSS) as secondary measures. Six weeks after injection the improvement in the Constant-Murley score was significantly greater in the methylprednisolone group (p = 0.003) than in the tenoxicam group. The improvement in the DASH score was greater in the steroid group and the difference was statistically significant and consistent two (p < 0.01), four (p < 0.01) and six weeks (p < 0.020) after the injection. The improvement in the OSS was consistently greater in the steroid group than in the tenoxicam group. Although the difference was statistically significant at two (p < 0.001) and four (p = 0.003) weeks after the injection, it was not at six weeks (p = 0.055). Subacromial injection of tenoxicam does not offer an equivalent outcome to subacromial injection of corticosteroid at six weeks. Corticosteroid is significantly better than tenoxicam for improving shoulder function in tendonitis of the rotator cuff after six weeks.

Corticosteroid injections for lateral epicondylitis: a systematic review

Patients with lateral epicondylitis (tennis elbow) are frequently treated with corticosteroid injections, in order to relieve pain and diminish disability. The objective of this review was to evaluate the effectiveness of corticosteroid injections for lateral epicondylitis. Randomised controlled trials (RCTs) were identified by a highly sensitive search strategy in six databases in combination with reference tracking. Two independent reviewers selected and assessed the methodological quality of RCTs that included patients with lateral epicondylitis treated with corticosteroid injection(s), and reported at least one clinically relevant outcome measure. Standardised mean differences were computed for continuous data and relative risks (RR) for dichotomous data. A best-evidence synthesis was conducted, weighting the studies with respect to their internal validity, statistical significance, clinical relevance, and statistical power. Thirteen studies consisting of 15 comparisons were included in the review, evaluating the effects of corticosteroid injections compared to placebo injection (n=2), injection with local anaesthetic (n=5), another conservative treatment (n=5), or another corticosteroid injection (n=3). Almost all studies had poor internal validity scores. For short-term outcomes (<or=6 weeks), statistically significant and clinically relevant differences were found on pain, global improvement and grip strength for corticosteroid injection compared to placebo, local anaesthetic and conservative treatments. For intermediate (6 weeks-6 months) and long-term outcomes (>or=6 months), no statistically significant or clinically relevant results in favour of corticosteroid injections were found. Although the available evidence shows superior short-term effects of corticosteroid injections for lateral epicondylitis, it is not possible to draw firm conclusions on the effectiveness of injections, due to the lack of high quality studies. No beneficial effects were found for intermediate or long-term follow-up. More, better designed, conducted and reported RCTs with intermediate and long-term follow-up are needed.

Local corticosteroid injection in sport: review of literature and guidelines for treatment

The risks and benefits of local injection therapy of overuse sports injuries with corticosteroids are reviewed here. Injection of corticosteroid inside the tendon has a deleterious effect on the tendon tissue and should be unanimously condemned. No reliable proof exists of the deleterious effects of peritendinous injections. Too many conclusions in the literature are based on poor scientific evidence and it is just the reiteration of a dogma if all steroid injections are abandoned. The corticosteroids represent an adjuvant treatment in the overall management of sports injuries: basic treatment is 'active' rest and graduated rehabilitation within the limits of pain. With proper indications there are only few and trivial complications that may occur with corticosteroid injections. Guidelines for proper local injection therapy with corticosteroids are given.

Shoulder complaints in patients with reflex sympathetic dystrophy of the upper extremity

Five hundred forty-one patients with reflex sympathetic dystrophy (RSD) of the upper extremity were prospectively studied. One hundred fifteen patients complained of pain and/or limited range of motion in the shoulder. Shoulder complaints more often occurred in women (p = .01); age and etiology were not different from patients with RSD without shoulder complaints. Physical examination showed a tendinitis of one or both tendons of the biceps muscle in 109 patients. Seventy one patients were treated with local injection of bupivacaine followed by methylprednisolone. This resulted in permanent relief of complaints in 34 patients, temporary or moderate relief in 31, no difference in 3, increase of complaints in 1 patient, and in 2 patients results were not documented. We conclude that shoulder complaints in RSD occur in a minority of patients and more often in female patients. There are no predisposing factors. The pathophysiologic mechanism for developing shoulder complaints remains unknown. In most cases complaints can be attributed to a bicipital tendinitis for which local injection of bupivacaine followed by prednisolone are both diagnostic and therapeutic.

Achilles tendon injuries in athletes

Two-thirds of Achilles tendon injuries in competitive athletes are paratenonitis and one-fifth are insertional complaints (bursitis and insertion tendinitis). The remaining afflictions consist of pain syndromes of the myotendineal junction and tendinopathies. The majority of Achilles tendon injuries from sport occur in males, mainly because of their higher rates of participation in sport, but also with tendinopathies a gender difference is probably indicated. Athletes in running sports have a high incidence of Achilles tendon overuse injuries. About 75% of total and the majority of partial tendon ruptures are related to sports activities usually involving abrupt repetitive jumping and sprinting movements. Mechanical factors and a sedentary lifestyle play a role in the pathology of these injuries. Achilles tendon overuse injuries occur at a higher rate in older athletes than most other typical overuse injuries. Recreational athletes with a complete Achilles tendon rupture are about 15 years younger than those with other spontaneous tendon ruptures. Following surgery, about 70 to 90% of athletes have a successful comeback after Achilles tendon injury. Surgery is required in about 25% of athletes with Achilles tendon overuse injuries and the frequency of surgery increases with patient age and duration of symptoms as well as occurrence of tendinopathic changes. However, about 20% of injured athletes require a re-operation for Achilles tendon overuse injuries, and about 3 to 5% are compelled to abandon their sports career because of these injuries. Myotendineal junction pain should be treated conservatively. Partial Achilles tendon ruptures are primarily treated conservatively, although the best treatment method of chronic partial rupture seems to be surgery. Complete Achilles tendon ruptures of athletes are treated surgically, because this increases the likelihood of athletes reaching preinjury activity levels and minimises the risk of re-ruptures. Marked forefoot varus is found in athletes with Achilles tendon overuse injuries, reflecting the predisposing role of ankle joint overpronation. Athletes with the major stress in lower extremities have often a limited range of motion in the passive dorsiflexion of the ankle joint and total subtalar joint mobility, which seems to be predisposing factor for these injuries. Various predisposing transient factors are found in about one-third of athletes with Achilles tendon overuse injuries; of these, traumatic factors (mostly minor injuries) predominate. The typical histological features of chronically inflamed paratendineal tissue of the Achilles tendon are profound proliferation of loose, immature connective tissue and marked obliterative and degenerative alterations in the blood vessels. These changes cause continuing leakage of plasma proteins, which may have an important role in the pathophysiology of these injuries. The chronically inflamed paratendineal tissues of the Achilles tendon do not seem to have enough capacity to form mature connective tissue.

Painful shoulder syndromes: diagnosis and management

Painful shoulder conditions are common primary care problems. Providers should learn the topographical landmarks about the shoulder and understand shoulder mechanics. A careful clinical evaluation will usually provide a likely diagnosis. In unclear cases with marked pain, weakness, and reduced mobility, or with a suspected rotator cuff tear or rupture, arthrography or MRI will usually establish a diagnosis. Therapy of bursitis/tendinitis consists of a steroid injection into the inflamed subacromial area or a 14-day trial of an NSAID. Therapy of bicipital tendinitis, largely empiric because definitive studies are unavailable for any specific treatment, includes judicious peritendinous steroid injections and avoiding aggravating activities. In the management of patients with suspected tendon tears or rupture, primary care practitioners can confirm the diagnosis by ordering MRI or arthrography before referring these patients to an orthopedist for definitive surgical therapy. Optimal management of adhesive capsulitis remains unclear, but an intraarticular steroid injection appears beneficial at least in temporarily diminishing pain. Pendular motion exercising is also an integral part of therapy. Deleterious effects of peribursal or intraarticular steroid infiltration appear minimal; but injections into the tendon or frequent, repetitive injections are contraindicated. Each shoulder condition has a variable course, depending on the structure(s) and extent of involvement.
